Description

Technical Field

[0001] This utility model relates to the field of refrigeration technology, specifically to the upper cover of an ice-making evaporator and the ice-making evaporator itself. Background Technology

[0002] An ice-making evaporator is a core component in a refrigeration system that outputs cooling capacity. The ice-making evaporator absorbs heat by vaporizing liquid refrigerant under low pressure, thus removing heat from the medium being cooled (such as water or air) to achieve a cooling effect.

[0003] The ice-making evaporator includes a lower support, a cylinder, an upper cover, an inlet pipe, an evaporation unit, a spiral ice-scraping mechanism, and an ice-breaking assembly. One end of the cylinder is fixed to the lower support, and the other end is fixed to the upper cover. The upper cover has an ice outlet hole. The inlet pipe is connected to the cylinder. The evaporation unit is disposed on the outer circumferential surface of the cylinder. A portion of the spiral ice-scraping mechanism is located inside the cylinder. One end of the spiral ice-scraping mechanism is rotatably engaged with the lower support, and the other end is rotatably engaged with the upper cover. The other end of the spiral ice-scraping mechanism is fixed to the ice-breaking assembly, which is located above the ice outlet hole.

[0004] Ice is extruded from the ice outlet by the spiral ice scraper mechanism to form ice strips. As the ice-breaking component rotates with the spiral ice scraper mechanism, it breaks the ice strips during rotation, thus obtaining the desired ice granules. However, a current problem is that insufficient extrusion pressure causes the ice strips to exit too quickly, forming cracks. This affects the appearance during use. If the cracks are too numerous and dense, the ice strips will prematurely break before the ice-breaking component can break them, resulting in smaller, pre-broken granules. From the user's perspective, these pre-broken granules are considered of low quality, leading to a decrease in the sales of ice evaporators. Utility Model Content

[0005] This invention provides an upper cover for an ice evaporator and an ice evaporator, which can greatly reduce cracks on ice strips output from the ice outlet.

[0006] The technical solutions to the above technical problems are as follows:

[0007] The upper cover of the ice evaporator includes an upper cover body, which has multiple ice outlet holes that extend through the upper cover body along its axial direction. The inner wall of each ice outlet hole has multiple toothed components.

[0008] An ice-making evaporator includes a lower support, a cylinder, an upper cover, an inlet pipe, an evaporation unit, a spiral ice scraping mechanism, and an ice-breaking assembly. One end of the cylinder is fixed to the lower support, and the other end of the cylinder is fixed to the upper cover. The inlet pipe is connected to the cylinder. The evaporation unit is located on the outer circumferential surface of the cylinder. A portion of the spiral ice scraping mechanism is located inside the cylinder. One end of the spiral ice scraping mechanism is rotatably engaged with the lower support, and the other end of the spiral ice scraping mechanism is rotatably engaged with the upper cover. The ice-breaking assembly is connected to the other end of the spiral ice scraping mechanism and is located above the upper cover.

[0009] In this invention, after a toothed component is provided on the inner wall of the ice outlet, the toothed component will create resistance to the ice strip. Since the ice evaporator pushes the ice strip from bottom to top through a spiral ice scraping mechanism, coupled with the resistance of the toothed component, the ice strip is subjected to pressure from both ends to the middle, which can compress the ice strip more tightly. Furthermore, the obstruction of the toothed component reduces the ice outlet speed, which not only greatly reduces the occurrence of cracks, but also prevents the ice strip from breaking prematurely. Under these circumstances, the appearance of the ice particles is improved, and the quality of the ice particles is enhanced. Attached Figure Description

Detailed Implementation

[0020] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0021] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0022] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0023] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0024] In this utility model, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0025] Example 1

[0026] like Figures 1 to 3 The first type of ice-making evaporator of this utility model has an upper cover A, which includes an upper cover body 1. The upper cover body 1 is provided with a plurality of ice outlet holes 2. The ice outlet holes 2 penetrate the upper cover body 1 along the axial direction of the upper cover body 1. The cross-sectional profile of the portion of the ice outlet hole 2 with toothed components 3 includes an outer curved segment 2a, an inner curved segment 2b, a first side 2c, and a second side 2d. The length of the outer curved segment 2a is greater than the length of the inner curved segment 2b. One end of the first side 2c is connected to one end of the outer curved segment 2a, and the other end of the first side 2c is connected to one end of the inner curved segment 2b. One end of the second side 2d is connected to the other end of the outer curved segment 2a, and the other end of the second side 2d is connected to the other end of the inner curved segment 2b.

[0027] Because the lengths of the outer curved segment 2a and the inner curved segment 2b of the ice outlet hole 2 in the above-mentioned structure are inconsistent, the ice strip entering the ice outlet hole 2 will experience inconsistent forces at the outer curved segment 2a and the inner curved segment 2b. As a result, the ice strip moves at different speeds at the outer curved segment 2a and the inner curved segment 2b, causing the ice strip to break prematurely. Therefore, in this embodiment, toothed components 3 are provided on the inner wall surface of the ice outlet hole 2. There are multiple toothed components 3. These toothed components 3 form resistance to the ice strip. Since the ice evaporator pushes the ice strip from bottom to top through the spiral ice scraping mechanism, coupled with the resistance formed by the toothed components 3, the ice strip is subjected to a squeezing force from both ends to the middle. This not only makes the ice strip more compact, but also reduces the ice outlet speed due to the obstruction of the toothed components 3. Based on the above, the premature breakage of the ice strip is avoided.

[0028] In this embodiment, the toothed component 3 is annular, and its thickness is 0.1-0.25 mm, preferably 0.15 mm. Adjacent toothed components 3 are spaced apart, forming a groove between them. The circumferential direction of the toothed component 3 can be parallel to the circumferential direction of the inner circumferential surface of the ice outlet 2, or it can form an angle with the circumferential direction of the inner circumferential surface of the ice outlet 2.

[0029] Example 2

[0030] like Figures 4 to 5 The difference between this embodiment and Embodiment 1 is that the portion of the ice outlet 2 with the toothed component 3 is a circular hole. A first groove 2e and a second groove 2f are provided on the inner wall of the ice outlet 2. The area enclosed by the first groove 2e and the second groove 2f is the toothed component 3. Both the first groove 2e and the second groove 2f are spiral grooves, with opposite rotation directions. The area enclosed by the intersection of the first groove 2e and the second groove 2f is the toothed component 3.

[0031] Example 3

[0032] like Figures 6 to 7 The difference between this embodiment and embodiment 2 is that: the first groove 2e is an annular groove, there are multiple first grooves 2e, there are multiple second grooves 2f, the angle formed between the extending direction of the second groove 2f and the axial direction of the ice outlet hole 2 is less than 90°, and the area enclosed by the intersection of the first groove 2e and the second groove 2f is a toothed component 3. In this embodiment, the portion of the ice outlet hole 2 with the toothed component 3 is a regular polygonal hole, such as a regular hexagonal hole, and the extending direction of the second groove 2f is parallel to the axial direction of the ice outlet hole 2.

[0033] Example 4

[0034] The difference between this embodiment and embodiment 2 is that the toothed component 3 is spiral-shaped.

[0035] like Figure 8 The ice-making evaporator of this utility model includes a lower support 10, a cylinder 11, an upper cover A, an input pipe 12, an evaporation unit 13, a spiral ice-scraping mechanism 14, and an ice-breaking component 15. One end of the cylinder 11 is fixed to the lower support 10, and the other end of the cylinder 11 is fixed to the upper cover A. The input pipe 12 is connected to the cylinder. The evaporation unit 13 is disposed on the outer circumferential surface of the cylinder 11. A portion of the spiral ice-scraping mechanism 14 is located inside the cylinder. One end of the spiral ice-scraping mechanism 14 is rotatably engaged with the lower support 10, and the other end of the spiral ice-scraping mechanism 14 is rotatably engaged with the upper cover. The ice-breaking component 15 is connected to the other end of the spiral ice-scraping mechanism 14 and is located above the upper cover A. The upper cover A is the upper cover A described in any of the above embodiments.
